Event Minimum Requirements

It is up to you what events you submit to Ratings Central, but here are the minimum requirements:

The event must have some sort of definite structure, for example, round robin, single or double elimination, team match, league match, ladder, winner stays. In other words, it must be more than just getting a bunch of players together and having each play whomever they wish. In particular, two players going to the club and playing each other half a dozen times is not an acceptable event.
You must submit all matches that are part of the event or tournament, not just some of them. However, if you wish to run an unrated novice event or some sort of “fun” event as part of your tournament, it is acceptable to submit the tournament and not submit the novice or “fun” event.
The event must be open to some segment of the public, for example, anyone who pays the entry fee, club members, students at your school. In other words, more than just your friends.
The event must be publicized in some way, for example, emailing entry forms, posting a notice on a club website, handing out fliers, posting a notice in your club.
You must do your best to collect accurate information (name, sex, country) on each new player and to correct any errors in such information for existing players.
You must inform players before they enter that the event will be submitted for ratings. However, historical backloads are exempt from this requirement; please for assistance.

You do not have to use Ratings Central ratings for seeding or eligibility, but of course, you are welcome to.
